Top songwriter collaborating with Kiwi artists has special praise for Lorde

She was rubbing shoulders with Beyoncé and Katy Perry at the Grammys last week.

But for the next five days, American writer Emily Warren is collaborating with Kiwi artists at Auckland's Roundhead Studios.

For the second year running, SongHubs has brought four international music writers to Auckland for a week-long workshop.

Warren's work on The Chainsmokers’ Don't Let Me Down earned them a Grammy for Best Dance Recording.

"It was crazy going to the Grammys for the first time and winning. It was just totally surreal," she told 1 NEWS.

"I was just shocked [when I saw Beyoncé]. I was five feet away from her at one point. That's actually crazy."

Warren also had special praise for Lorde, who released a teaser yesterday.

"She's amazing. An amazing lyricist and just such a cool perspective. I wonder how all the success affects the creative process, I'm really interested to see that."
